|Secret Blood Feast|
Begin by talking to Randal Cosca at the western side of Seraphina Palisades. He invites you to enter Randal Du Cosca's Flat and drink some human blood and Hema. Enter the house behind him and go to the east and drink the blood. Be careful for the 2 level 60 paranoid vampires, who can be evaded by standing behind the bar. After you've gathered the drink, return to Randal Cosca outside and tell him about the paranoid vampires. Mission complete!
